The Arteck Universal Keyboard connects with just about every Bluetooth device: iPad Air, iPad Mini, Android, MacOS, Windows Tablets, PC Smartphones and more. The Arteck is Amazon’s number one bestseller due to its compatibility, design, battery life and affordable price.
Most of the other keyboards listed here use battery power directly from the mobile device you use to connect it with. The Arteck has a rechargeable lithium battery with an industry-capacity of half a year between charges based off two hours of use per day with the backlight off.
It’s thin and light, weighing less than six ounces and measuring 9.3 x 5.3 x 0.4 inches. Unfortunately, unlike many other keyboards on the list, it doesn’t dock your device, so you won’t have that laptop style transformation.
The Arteck comes with a USB charging cable, welcome guide and a 24-month warranty, along with customer service. The device comes in seven LED backlight colors that you can change based off your preference (red, light green, green/yellow, purple, cyan, green and blue).
As another top keyboard, the OMOTON Ultra-Slim Bluetooth Keyboard combines ultra-portability and streamlined design at a very appealing price point. While it is compatible with any Bluetooth 3.0 device (including Android phones and tablets), this keyboard is designed with Apple products in mind and connects effortlessly to a wide range of Apple devices. It has 13 customized “hot keys” that allow you to control things like volume, music and brightness levels from your keyboard, and is capable of supporting several different languages like Korean and Japanese. It also maintains its connection up to 33 feet away from your device.
Unlike many of its competitors, this keyboard runs on two AAA batteries, meaning it won’t drain your device’s power to recharge and has a battery life of up to six months. With dimensions of 11.2 x 4.7 x 0.2 inches and a weight of only 10 ounces, this keyboard is perfect for frequent travelers and those who want to type more comfortably on the go.
The Universal Foldable Keyboard by Microsoft is a wireless keyboard that works with your iPad, iPhone, Android, Windows tablets and phones. It utilizes the latest in Bluetooth 4.0 technology, which winds up consuming less power. The ultra-thin and lightweight device only weighs one pound and measures 6.1 x 5.3 x 1.1 inches – and still has a full-size keyset for fast and accurate typing. Once folded, the keyboard becomes roughly the size of a wallet.
Its power system is simple and straight forward: Unfolding the keyboard powers it up, and closing it shuts it down. And the other features? It’s spill-resistant with a water-repellent keyset and fabric that’ll help against any coffee accidents. The keyboard does have a rechargeable battery, however, you can use it for up to three months on a single charge.
Some downsides of this product? The folding gap in between the keyboard might take some getting used to, and if you wind up using this for your Android device, you may have to pair it up each time you turn it on.
Made for your iPad Air (5th Generation), the Logitech Ultrathin Keyboard cover comes with built-in Bluetooth connectivity, full-size keys, and iOS shortcuts for fast typing. Its price tag is hefty, but where it falls short on its expenses it makes up for with sturdiness and functionality.
The Logitech Ultrathin Keyboard keeps your iPad in place similar to the Apple iPad Keyboard. Instead of docking your device, though, it has magnetic grooves to hold your iPad upright at the perfect angle for typing and interacting with your touch screen. The device houses and protects your iPad in a thin yet durable aluminum casing, and can close together with its powerful magnetic clips, keeping the cover and iPad perfectly aligned and secured.
One of the most troubling features of any iDevice is the tedious way of copying, pasting and undoing, and this keyboard makes up for that by including shortcuts for all three functions. It also comes with an auto wake/sleep feature that powers your iPad on when you open up the case and sleeps when you close it. Colors comes in space grey and white.
Our pick for best design is the Arteck Stainless Steel Universal Bluetooth Keyboard. This stainless-steel keyboard is compact at 11.1 x 5.3 x .16 inches and weighs just 10.2 ounces, so you can bring it just about anywhere. It offers six months of battery life on a single charge, which is just plain amazing. And it offers a more ergonomic design than other keyboards in this category with low-profile keys and comfortable typing that won’t cramp your hands.
The Anker Ultra Slim is our most compatible for a very simple reason: this thing is optimized to work for iOS (including all iPads and phones), Android, Mac OSX and Windows. But it’s also super light, clocking in at the same weight as a standard billiard ball. It’s ultra-slim at 4.8 x 11.18 x 0.73 inches, and it lasts almost three months on just one set of two AAA batteries -- based on two hours of use per day. And the best part? This Bluetooth connecting keyboard is well under $20, so you aren’t going to have to break the bank to stay compatible with all your devices.
Layout - Before you decide on a keyboard layout, you'll want to consider how much room you have on your desk and how portable you want the keyboard to be. A standard keyboard will have arrow/navigation keys, function keys, a numpad, and perhaps even programmable keys, while a TenKeyLess keyboard—what you find on most laptops—lacks a numpad. There are a variety of layouts, so consider how compact of a keyboard you want.
Backlighting - Gamers will likely value backlighting more so than a business user. However, if you think you’ll be spending dark nights hunched over your keyboard, backlighting is something you should consider. Some models even offer the option to change the color of the backlighting, although that drains the battery life faster.
Ergonomics - Comfort is crucial in a keyboard because you’ll probably spend a good chunk of time in front of it. Keyboards with adjustable height and tilt often provide a better typing angle for your wrists. If the keyboard doesn’t come with a built-in wrist rest, you can always consider buying a separate one.
